Shopify Webhooks

When to Use This Skill

• Setting up Shopify webhook handlers
• Debugging signature verification failures
• Understanding Shopify event types and payloads
• Handling order, product, or customer events

Verification (core)

Shopify signs the raw body with HMAC-SHA256 keyed on the app's API secret and sends the digest in X-Shopify-Hmac-SHA256 as base64 (not hex). Pass the raw body, decode base64, and compare timing-safe. The topic is in X-Shopify-Topic; the shop domain in X-Shopify-Shop-Domain.

Node:

const crypto = require('crypto');

function verify(rawBody, hmacHeader, secret) {
  if (!hmacHeader) return false;
  const expected = crypto.createHmac('sha256', secret).update(rawBody).digest('base64');
  try {
    return crypto.timingSafeEqual(Buffer.from(hmacHeader), Buffer.from(expected));
  } catch {
    return false;
  }
}

Python:

import hmac, hashlib, base64

def verify(raw_body: bytes, hmac_header: str, secret: str) -> bool:
    if not hmac_header:
        return False
    expected = base64.b64encode(
        hmac.new(secret.encode(), raw_body, hashlib.sha256).digest()
    ).decode()
    return hmac.compare_digest(hmac_header, expected)

Important: Shopify requires the endpoint to respond with 200 within 5 seconds. Process work asynchronously if the handler is slow.

For complete handlers with route wiring, event dispatch, and tests, see:

• examples/express/
• examples/nextjs/
• examples/fastapi/

Common Event Types (Topics)

Topic	Description
orders/create	New order placed
orders/updated	Order modified
orders/paid	Order payment received
orders/fulfilled	Order shipped
products/create	New product added
products/update	Product modified
customers/create	New customer registered
app/uninstalled	App removed from store

For full topic reference, see Shopify Webhook Topics

Note: While the REST Admin API is becoming legacy for apps created after April 1, 2025, existing apps can continue using the REST API. New apps should consider using the GraphQL Admin API for webhook management.

We recommend installing the webhook-handler-patterns skill alongside this one for handler sequence, idempotency, error handling, and retry logic. Key references (open on GitHub):

• Handler sequence — Verify first, parse second, handle idempotently third
• Idempotency — Prevent duplicate processing
• Error handling — Return codes, logging, dead letter queues
• Retry logic — Provider retry schedules, backoff patterns
